It will end Nissan's 20-year exile from the series and, along with the inclusion of Mercedes, represents the biggest shake-up of the V8 Supercar era - made possible by its Car of the Future scheme.

The existing Kelly Racing Team will be rebranded Nissan Motorsport from January 1 and marks the first time that the brothers will have sat in anything other than a Holden in their Supercars careers.

Unlike the engines found in the rival Falcon and Commodore, which rely on pushrod cam technology and only two valves per cylinder, the Nissan powerplant benefits from a double overhead cam design with four valves per cylinder. The engine, whose performance has already been proven in the Nissan GT-R GT1 racer, also features electronic fuel injection and a MoTeC ECU.

Note, due to the benefits of its engine design, Nissan will work closely with V8 Supercars on achieving a fair playing field. In addition to the 5.0-liter displacement limit, the engine also must have an rpm limit of between 7,000 and 7,500 revs, an output of around 650 horsepower and a torque curve that’s in parity with its rival units from Ford and Holden.
